Question

When a force of 30 N acts on a certain object the acceleration of the object is 5m/s2 if the force is changed to 54 N what will be the acceleration of the object

Answer 1

The correct answer is 9 m per
`second^(2)`

Explanation:

Force is defined by mass of an object times it's acceleration.

Let the mass of the object be m kilograms.

When a force of 30 N acts on a certain object the acceleration of the object is 5 m per
`second^(2)`

∴ 30 = m × 5

⇒ m = 6.

If the force is changed to 54 N, let the acceleration of the object be x m per
`second^(2)`.

∴ 54 = m × x

⇒ x =
`(54)/(6)` = 9

Thus when the force is 54 N, the acceleration of the object is 9 m per
`second^(2)`.
